Patch Features

New System: Monster Power
Similar to the "Players X" command in Diablo II, Monster Power is a system designed to give players more control over how challenging enemies are in each difficulty. With this system, players can choose to increase the health and damage of monsters according to different "power levels" and in return they'll receive scaling bonuses to experience as well as boosts to Magic Find and Gold Find which will stack above the 300% cap. The option to increase Monster Power will be available to all players starting at level 1 in the Quest Selection window, and can be adjusted separately for Normal, Nightmare, Hell, and Inferno difficulties.

For more information on how to enable and use Monster Power, click here!

New Event: Infernal Machine
The Infernal Machine is a device that will allow level 60 players to battle "uber" versions of some of Sanctuary's most nefarious bosses. While the rewards for defeating these bosses will be great, some assembly is required. Only the most powerful Nephalem can unlock the secrets to building the Infernal Machine,  but once forged the device can be used to open portals to special encounters featuring not one, but two bosses which have been augmented from their original versions, both in terms of difficulty and appearance. Defeating each boss pair will provide players with extra items and gold, as well as a chance to find components for a new Legendary ring. 

General

• Resplendent Chests will now operate similarly to Elite packs in Inferno difficulty:
  • When players open a Resplendent Chest, they will receive a reward based on how many Nephalem Valor stacks they have active at the time
  • Opening a Resplendent Chest will grant one stack of Nephalem Valor
• Major in-game events will now grant one stack of Nephalem Valor when completed by a level 60 character in Inferno difficulty
  • If completed in a multiplayer game, all eligible characters in the party will receive the buff regardless of whether they participated in the event or were close to the event's location
• Major in-game events in Inferno difficulty that involve a special chest or Unique monster will now also drop additional loot for every stack of Nephalem Valor a player has active at the time of the event’s completion
  • Several events have had Unique monsters added to them for this purpose
• Experience Shrines can now appear in Inferno difficulty
• Two new shrines have been added to all difficulty levels:
  • Empowered Shrine – Increased resource regeneration and reduced cooldowns
  • Fleeting Shrine – Increased movement speed and pickup radius
• Followers, pets, and summoned creatures will no longer attack enemies that are in an idle state unless the player is within 10 yards of the enemy (note: Hydra heads and Sentry turrets are not affected by this change)
• The reduction of snare effects against Elite monsters has been reduced (in the player’s favor):
  • Normal: 20% to 0%
  • Nightmare: 30% to 15%
  • Hell: 40% to 25%
  • Inferno: 40% to 25%
• Crowd control effects will now be affected by diminishing returns. To learn more about how diminishing returns will work in Diablo III (and why these changes are an overall buff to player CC), click here!

Auction House

• Search parameters will now save when switching  between the gold and real-money auction house
• An additional sortable column has been added to the results window
  • This column will have a drop-down box populated with each of the Preferred Stats that players indicated for their search (only one Preferred Stat can be selected at a time)
• The Preferred Stat list is now sorted alphabetically
• A button has been added to allow players to quickly reset Preferred Stat filters to "None"
• Players can now search for +Damage on off-hand items
• When searching for items to purchase, an option to "autofill" stats based on what the player is currently wearing has been added
• Similarly, when selling an item, a "Find Similar" button has been added to allow players to quickly search for items currently up for auction that have similar stats
• An option to display Auction House events (sales, expirations, etc) has been added to the Social menu
• Bug Fixes
  • When claiming stackable items from the auction house, the claimed items will always attempt to fill out partial stacks completely before falling back to using an open slot in your inventory
  • The color-coding for the "Quality" drop-down menu for Pages & Recipes has been updated to match the color-coding for all other categories
  • Fixed a bug that was causing the minimum value for the Spirit Regen affix to not filter items correctly

Battle.net

• The "Friend of Friend" feature for finding and adding Real ID friends is now available for Diablo III
• A new item delivery system has been added that will allow Blizzard to send license-based items directly to players, for example: Collection's Edition rewards (you may see us testing this feature over the course of the PTR)
• Achievements
  • An Achievement button has been added to the in-game hotbar
  • Players can now link Achievements in chat

  • Players can now customize their banner in-game while in town

  • Players can now change font color (per channel) and size
  • Clicking on items linked in chat will now provide a comparison tooltip based on what you are currently wearing

  • To leave a party while in-game, right-click on your hero portrait and select "Leave Game & Party"
  • To leave a party while in the hero screen, right-click on your hero and select "Leave Party"

Hey guys, thanks for your posts and, more importantly, your patience!

We are actively working on bringing the PTR back up. It's the first one ever for Diablo III, so it's a little rough around the edges. I'll post back when I have some more info.

The currently goal is to get the PTR back up by the end of today so you guys can check it out before Mists of Pandaria launches.

Update 10/11/12 6:00 p.m. PDT: PTR status is online.

Patch 1.0.5 is currently in development and now available for testing on the PTR. This patch introduces Monster Power, a new system which will allow you to adjust how challenging monsters are across each difficulty, and the Infernal Machine, an event that will pit players in Inferno against "uber" versions of some of Sanctuary's most nefarious bosses. Patch 1.0.5 also includes several bug fixes, UI improvements, and additional class and item balancing. 

PTRs are a very valuable tool for our development teams -- when you participate, share your feedback, and submit reports, we can squash more bugs and ensure that the patch we release is of the highest quality possible. Patch 1.0.5 will mark the first time we've performed a public test for Diablo III, but we’re planning to conduct public tests for most (if not all) future patches. 
 

How to Participate:

To participate in the public test, you must have a Diablo III game license attached your Battle.net account that’s in good standing (i.e. it hasn’t been suspended or banned). While the 1.0.5 PTR is only available in English, French, German, and Korean languages, accounts from all regions are eligible to participate.

Step 1: Create a PTR account by logging in to your Battle.net Account Management page. Select your Diablo III game license, and then click "Create a PTR account."

Step 2: Download the client from the Diablo III landing page, or from your Games Download page in Account Management.

Step 3: To play on the PTR, simply launch the PTR client and log in normally. You will be connected to the PTR server automatically.

Character Copy:

The option to copy your existing Diablo III characters from your live account to the PTR will be available and can be done directly through the PTR client. However, only one region per account can be copied at a time. So, if you choose to copy characters from your account in a different region, any previously copied PTR characters will be lost.

Step 1: Log into PTR client and create a level 1 character. After you're done, return to the main character screen.

Step 2: Click on the "PTR Copy" button located in the upper right-hand corner. (The PTR Copy button will not appear in-game until you have created a new level 1 character.)

Step 3: Select your region.

Step 4: Click "Copy." This will copy all characters on your account from the selected region.

Step 5: You will be disconnected from the PTR client.

Step 6: Log back in. Your copied characters will be available for play.

Please note that you can only copy characters over to your PTR account once every 72 hours. Attempting to copy characters more than once per week will result in Error 395000.
 

Further details on how to access the PTR and use the Character Copy system can be found in the FAQ.  Once you've had the chance to try things out, be sure to visit the Public Test forums to discuss the patch.

As this is a test server, please anticipate uneven game performance, and note that restarts and downtime may occur without warning. We'll provide information regarding extended downtimes, should they occur, in the PTR Feedback forum.
